Thermoplastic

Thermoplastic is flexible and can change forms when it is heated it turns into a liquid and when it cools it becomes a substance much like glass. Thermoplastics are handy because they are able to be remelted which makes them recyclable. Every thermoplastic had a different weight and also differs in crystalline. The only thermoplastics made today are poleythane polypropethene and polycarbonate. Today thermoplastics are used to make guitar picks.
